HILLSBORO, Oregon - On December 18, 2018, Judge Charles Bailey sentenced Robert Alan Stewart to 75 months in prison after he pleaded guilty to Rape in the Second-Degree.

This case began in 2013, when Stewart met his female victim online. He was 27-years-old at the time but claimed to be 19. His victim was 13-years-old. He gave the victim alcohol and marijuana and engaged in sexual intercourse with her several times.

The crimes didn't come to light until 2018, when a School Resource Officer with the Tigard Police Department learned of possible abuse involving the victim. Detective John Shipley of the Washington County Sheriff's Office took over the investigation and arrested Stewart a short time later.

Stewart was also convicted of Sexual Abuse in the Second-Degree in 2014 in an unrelated case also involving a juvenile victim. Based on this pattern of conduct, investigators fear there could be additional victims.

Anyone with information related to possible crimes involving Stewart should call law enforcement right away. You can also report these types of crimes anonymously by calling the Child Abuse Reporting hotline at 503-731-3100.
